Complaint Review: gm

This is to address a frustrating experience with GM since I bought my (then brand new) Envoy 2006. I experienced a problem with my car for the first 3 years I bought it. Besides other smaller issues, my car came with a noise that would come from the back seats or somewhere around. Cutting the very long history short (I am pretty sure GM has everything on file - I Do!) none of the GM assistance in Kissimmee or Orlando were able to find the cause of that noise. After many years, time consuming, work hours lost and stressful and frustrating situations, my husband and I gave up trying and just kept the car like this, knowing that anytime we will try to sell it the buyer will complain and we will loose money right there. The funny and irritating part is that we had the GM warranty for the first years, GM was NEVER able to fix the issue that came from the plant with the car, and then I was told that the car was not in the warranty anymore, therefore I could have no assistance without paying!!! I cannot even start to explain the anger and the feeling of betrayal as a customer, and for such an expensive matter. It is not that we bought a pen in a dollar store!!! Time goes by and now I see myself unbeliaveble-ly going through the very same situation, just the car issue changed (by the way, my 9 year old son found out what is the problem, the sound comes from the back panel control for the radio and ac...
The check engine light started going on and off about 1 year ago, and, because it would sometimes be off for weeks, even months, we did not bother until it started being on more often and the fuel sensor stopped working. I took it to Advanced Auto care to do a check and it accused that it was the fuel sensor ( I just wanted to make sure I had the reading from another place other than GM since my prior experience does not allow me to trust GM service). It was when I learned that there is a "light recall" or however GM calls it, for this problem. I called GM, spoke to Mrs. H, and she sent me to Fountain Auto Mall in Orlando (I know well that place, unfortunately). They confirmed the problem was the fuel and they "fixed" the sensor. however, the check engine light keeps going on and off, basically after a little while when I put gas in my car. Mr. R. from GM customer service, at this point was following up with calls etc.. and I spoke to him about the issue. Fountain Auto Mall set up an appointment for me to take the car back (here I go all again) to check. I did so yesterday (April, 6 2012) and - surprisingly (I am being sarcastic) they told me that the engine light on means "low idle" and it is not the same issue w/ the fuel sensor issue therefore there is nothing they can do for me and I should pay (how convenient) $99 just to check why the idle is low.......Kidding? Any 9 year old would know better that low idle comes also from the fuel pump, fuel filter or such and what a coincidence they touch my car and now this..... believing that Gm could redeem itself from previous experience I trusted that Mr. R. would assist me by allowing further check on my car, fair enough, to make sure the low idle IS due to the fuel system (which they DID NOT fix, clearly), I contacted him, who, not only was very unhelpful, but sarcastic and anti professional, telling me that my car is not new and I will have problems with the car from now on....This not only underestimate my intelligence as put me more frustrated.....I WILL have problems w/ my car SR.? I ALWAYS had problems w/ my car since I bought it.... I understand that Gm customer service personnel needs to close their "cases" and better if it is as soon as possible to get rid of issues and to have one more case solved in their pile, however, my case Sr. is far from being closed. It does not even matter the fact that OF COURSE this was the first and last time me and anybody else I know will not buy GM or affiliated cars never more in life, but I am not going to be fooled again by GM. I am going further on this, I want nothing else than my car problems caused by GM's lack of professionalism and knowledge to fix he cars, to be fixed, any other issues I had w/ my car, I took care of, I pa I have the right and proof enough since the beginning, all paperwork, more than 20 times I took my car to service. I want you to know that Gm can pretend to care for its customers by calling, flowering the customer service in talking, following ups etc.. but this is all for your eyes only. Gm does not do anything for customers just pretend it does, and, like every single situation in life one day the curtain falls and the faces come up. I feel disrespected and being forced to pay for a service that, not only is GMs responsibility, but I would not choose to fix my car should I pay for it. GM authorized service touched my car and either created another problem or did not fix the problem in the corrected way, for the 20th time, and I have to hear from the customer service rep. that my car is going to give me problems.
I will search for assistance in this matter, this is the minimum I can do to make it right and worth to have bought a car 0miles, brand new and never had the feeling.
